ORE CLASSIFIER.

Application filed Gctober 4, 192-9. Serial N'o. 414,395.

To all whom it may concern:

Be it known that I. ALBERTO Nom nee. a citizen of the Republic of Peru,residing at New York city, in the county of New York and State of NewYork, have invented new and useful Improvements in ()re Classifiers, ofwhich the following is a specification.

This invention relates to ore classifiers and one of the principalobjects is to pro duce' a device of this nature which shall be simple ofconstruction. comparatively. inexpensive to manufacture, and cflicientvfor the purpose for which it is designed.

Another object is to provide a plurality of co-acting conical membersfor receiving and directing the differently separate members, a

Another object is to provide an improved agitating means for the conicalmembers.

Anotherv object is to provide a simple adjusting means for saidagitating means.

Other objects will appear hereinafter.

All of these objects are accomplished by means described andclaimedhereinafter and fully illustrated in the accompanying drawing comprisingtwo sheets, in which Figure 1 is a vertical sectional view of myimproved ore classifier.

Figure 2 is a top plan view of the distributing cone.

Figure 3 is a top plan view of the entire device.

Figure 4- is atop plan view of the col lectlng ring.

Figure 5 is a detail view of the overflow gate.

Figure 6 is a detail view of the adjustable members of the agitatingdevice;

Figure 7 is a detailview of oneof the spring seats Figure 'Sis a detailview of one of the adjustable distributor retainers.

Like characters ofreference parts in alllviews.

This invention contemplates providing an oreclassifier in which the orecrushed and mixed with water is discharged onto a vibratory cone fromwhich it is distributed against the-side walls of; a funnel shapedreceiver which is filled with waterhaving an upward current and whichwashes away the small and lightparticles, the heavier denote like andlarger particles rebounding from the sides of the receiver to difi'erentdistances are caught by suitable separating means and directed todifi'erent receptacles.

.Referring more particularly to the drawing, 1 represents the frameworkwhich is shown as constructed of wooden beams but which may be of anysuitable material. and

.construction to support the mechanism hereinafter described. Theframework 1 is provided with metal members 2 having collarsor springseats 3. Mounted in these spring seats are the lower ends of a pluralityof spiral springs 4, the upper ends of which are secured to and supportan annular member 5 through an opening in the center of which afunnel-shaped receiving member 6 protrudes. The members 5 and 6 aresecured togetherin any suitable manner so as to form a trough 7 saidtrough being inclined toward a spout or delivery element 8. A cover 9may be hingedly or otherwise secured to the member 5.

. The funnel 6 is provided near its bottom with an outlet 10 controlledby a valve 11, and is provided with an inlet 12 controlled by a valve 13for permitting the inflow of water from a pipe or hose 14. The funnel 6is provided at'its top with an aperture or slot in its edge. Adjacent tothis slot flanges 15 extend into the funnel from the sides thereof andare connected by pins 16. In the guideways formed by flanges 15 andbetween the side of the funnel 6 and the pins M3 is inserted a pair ofoppositely inclined slides 18 by sliding which toward. or away from eachother the level of the water in the funnel is regulated. A glass 19 isset into the side of funnel 6 to permit the operator to view theinterior.

Mounted in the base of the funnel 6 is pipe 20 controlled by a valve 21and having secured to its upper end a collecting funnel or cone 22.

A pipe 28 conducts pulp to a discharge nozzle 24 and is provided with acontrolling valve 25. This pipe, passes through an aperture 26 in thecover 9, said aperture being large enough to permit relative movement ofmembers 9 and 24. From nozzle 24 the pulp is discharged onto a conicaldistributing plate 27 provided with directing ribs '28 which divide thepulp and lead it against various portions of the Wall of the funnel 6.Near the periphery ofcone 27 bolts 29 ass through said cone and alsothrough 5 ots 30 in members 31, said members being rounded at 32 andadapted to be seated against the wall of the funnel 6. By extendingthese members to a greater or less extent the plate 27 may be adjustedto a higher or lower position in the cone or funnel 6, increasing orreducing the space between the edge of the cone 27 and the wall of thefunnel.

An auxiliary pipe 33 is controlled by a valve 34 to permit the use ofmore water when desired.

Mounted slidably. in bearings 35 in the top 9 and passing freely throughsleeves 36 in the distributor 27 are vertical rods 37 which are screwthreaded at their upper ends.

and provided with adjusting wheels or handles 38. Secured to the lowerends of rods 37 is a deflector ring or truncated cone 39.

Secured toa shaft 40 which may be rotated by any desired means is a camwheel 41 provided with a plurality of cams or lugs 42. I

Secured to the outer side of the cone 6 is a member 43 having a lug 44adapted to be operated upon by the cams 42 to effect vibration of thecone 6 and the devices supported thereby. The inner face of the member43 is provided with a plurality of serrations45 which are adapted toco-act with teeth 46 011 a wedge member 47 inserted between member 43and the cone 6. By adjusting the teeth and serrations the wedge 47 will,hold the lug 44 further out and thereby agreater agitation of thedevices will be efi'ected by the cams 42.

The cone 22 is adjustable vertically to any desired height in the cone 6and may be brought low enough to entirely close off the flow of waterfrom pipe 12. Packing 50 forms a tight closure around 20 and screw 51will hold funnel 22 in any adjusted position.

In operation the pulp is discharged onto distributor plate 27 and movesdownwardly thereon into the water in the cone 6. The water circulatingupwardly from inlet 12 washes the small and light particles out throughthe gates 18 into the trough 7 and out through spout 8. The larger andheavier lumps will roll against the sides of cone 6 and reboundtherefrom being collected by ring 39 and directed into the receptaclefunnel 2.2 from which they may be drawn off through pipe 20 and valve21. The intermediate particles will follow down the sides of the funnel6 and may be drawn ofi through outlet 10 and valve 11. The cam devicekeeps the cone 6 and connected parts in vibration so as to preventjamming or clogging of the parts. By adjusting the height of the plate27 and the ring 39, the size of the lumps received by the receptaclesmay be varied.

It is of course understood that by the use of more cones and deflectorrings, a greater variety of grading may be obtained.

While I have described what I deem to be the most desirable embodimentof my invention, it is obvious that many of the details may be variedwithout in any Way departing from the spirit of my invention; and Itherefore do not limit myself to the exact details of constructionherein set forth nor to anything less than the whole of my inventionlimited only by the appended claims.

What I claim as new and desire to secure by Letters Patent is 1. In adevice of the class described the combination of a plurality ofconcentric receptacles, means for maintaining a fluid level in saidreceptacles, means for discharging pulp into said receptacle, a conicaldeflector plate for receiving the discharged pulp and directing itagainst one of said receptacles to effect variable rebound of theparticles, said platebeing arranged with its edge below the fluid level;and means for varying the fluid level for varying the rebound. e

2. In a device of the class described, the combination of a conicalreceptacle, a second conical receptacle, means for discharging pulp intothe first said receptacle, a distributing plate'adapted to receive saidpulp from said discharging means and to direct the same toward the wallof the first said receptacle, and a collecting ring adapted to catchcertain portions of said pulp and direct the same into the said secondconical,

pulp into the first said receptacle, a dis-.

tributing plate adapted to receive said pulp from said discharging meansand to direct the same toward the wall of the first said receptacle, acollecting ring adapted to catch certain portions of said pulp anddirect the same into the said second conical receptacle, and adjustablesupporting means for said ring.
